An investigation into frictional surface interactions and their effect on brake judder.
… chemical nature of the Transfer Film (T.F.) or Third-Body Layer (T.B.L.) formed at the friction interface of an automotive friction brake during off-brake motoring has been studied using Energy Dispersive X-ray (E.D.X.) analysis and Scanning Electron Microscopy (S.E.M.). Although these …

Effect of Wheel and Rail Conditions on Contact Dynamics and Mechanics
This study uses the Virginia Tech – Federal Railroad Administration (VT-FRA) Roller Rig to assess how different running conditions affect the wheel-rail interface (WRI) dynamics and mechanics under repeatable and precise test settings. The advanced roller rig is used to emulate wheel loads, lateral …
